Delete and get the magnaflow Xpipe to reduce the rasp there's really no drone at high way speed's that I noticed and i have been driving mine for over a year and like 6 month's untill i got my BBk's a few month's ago then the rasp just got crazy it would sound like i had a bunch of dying cat's in my under carriage since then i got my Xpipe from magnaflow and it's A ok!!!

Granted mine is the LFX engine but I deleted my cats and like the sound. The drone does get kind of annoying. Im trying to find something that will cut out the drone. I am debating between resonated Xpipe or Jpipes.

I enjoyed my miffler delete. I cut off the mufflers about 2" from the weld. Installed 3" pipe from there. I ran about 10000 miles with this and enjoyed the sound drone at 75 was tollerable to my ears. Sounded bad outside but great in the cabin. Since then i added 12" long 3" id bullet style mufflers. Deepend the sound and killed some rasp. Sounds better outside and even better inside. I plan to dump the exhaust behind the wheels some day and plug the holes in the diffuser.

I dont care what it sounds like outside. From the drivers seat at wot is where it counts for me.
